Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 082 Issued at 2200Z on 23 Mar 2009
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity was very low.  No flares were observed
during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was quiet. Solar wind velocities at ACE ranged 
from 361-438 km/s, while the IMF Bz ranged between -3 nT and +7 nT.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly quiet for the next three days (24-26
March).
